3.10.15-r1 and 3.10.16-r3 still have sys-apps/hotplug dependency hardcoded with USE=usb, that needs to die. (There's also lots of other redundant versions in the tree, while at it...)
Taking over. Michael you let this package rot so much, since I need it, I'm going to take it over and take care.
Please don't say I didn't give you enough notice, last year I already asked you this much and now I'm simply tired.
This has FINALLY been fixed! Have a party!
